Question:

A mother who has a fraternal twin is this times more likely to have twins of her own?

Response:

2.5 times more likely to have twins

Feedback:

Fraternal twins come from two separate eggs that are released at once, so a mother’s genetics are involved. This means that there is a higher likelihood that her daughter would also have fraternal twins. In contrast, identical twins come from a random splitting of one fertilized egg, so there would be no increase in likelihood of twins in the next generation.
